Making its debut as the first member of a new series of threadleaf Coreopsis is this brand new red flowered selection from master hybridizer Darrell Probst.
Deep wine red to ruby red flowers with an orange center measure about 1½” across and completely cover the deep green, threadleaf foliage. Since the flowers are sterile, they appear over a long period from early through late summer and if cut back, the plants can be encouraged to rebloom until frost.
Compared to other threadleaf types, this plant has darker green foliage and is more clump forming, producing fewer rhizomes. Compared to ‘Mercury Rising’, this plant has finer threadleaf foliage, solid red flowers that do not become “frosted” in the heat, and a tighter mounding habit.
'Red Satin' has proven to be hardy to zone 5, a permanent threadleaf form as its series name suggests.
Coreopsis is easy to grow, making it a good choice for beginners. One plant will provide you with long-lasting cut flower bouquets all summer long.
